She adds: “I may not have taken the usual route to become a mum, but I didn’t want to settle with the wrong person and regret it in the future.”

As for her son, Mill says she hopes he understand her reasons for choosing to go down the sperm donor route.

“I wanted [Oliver] so badly that I needed some help from someone,” she says. “I intend on telling Oliver as soon as he is old enough to understand, I think he will appreciate the video I did as it shows how much I adored him before he was even here.”
